xe sr-create type=ext results in backend failure












0















I'm trying to create an ext based storage repository:



xe sr-create content-type="local SR" 
host-uuid=c7030a1f-15e3-7e7d-2932-b30200a15917 type=ext
device-config-device=/dev/sdb1
shared=false name-label="Local File SR"


Results in:



There was an SR backend failure.

          Editing util.py



          vi /usr/lib/xcp/sm/util.py


          and adding a print debug output statement:



          def doexec(args, inputtext=None):
          """Execute a subprocess, then return its return code, stdout and stderr"""
          print ', '.join(args) # Added print statement for debugging

          (stdout,stderr) = proc.communicate(inputtext)
          rc = proc.returncode
          return (rc,stdout,stderr)


          returned this output when running the sr-create command:



          stdout: sginfo, -s, /dev/sdb1
          /lib/udev/scsi_id, -g, -s, /block/sdb

          From this I could see that lvm tools are being used by sr-create.

          These tools were missing on my system. Installing apt-get install lvm2 resolved the issue for me.

                return (rc,stdout,stderr)


                returned this output when running the sr-create command:



                stdout: sginfo, -s, /dev/sdb1

                /lib/udev/scsi_id, -g, -s, /block/sdb


                From this I could see that lvm tools are being used by sr-create.





                Problem Solved



                These tools were missing on my system. Installing apt-get install lvm2 resolved the issue for me.
